Abstract

PURPOSE: To perform doubling, etc., of PCM signals easily and surely by providing digital input and output terminal f parts in input and output parts of a PCM recorder respectively.
CONSTITUTION: The PCM modulation signal reproduced by VTR8a is demodulated by demodulation part 23 whose clock phase is controlled by PLL16' of a PCM recorder, and one becomes an analogue signal through DA conversion part 24, and the other is outputted directly from a digital output terminal. This demodulation PCM signal is inputted from the digital input terminal of another PCM recorder and becomes a modulation PCM signal through switch 32 by modulation part 22 similarly to a signal, which is inputted from the analogue input terminal and is converted to a PCM signal by A/D converter 21, and is doubled onto VTR60. Consequently, doubling is performed easily without returning this signal to the PCM signal and the analogue signal and converting this signal to a PCM signal again by A/D conversion, and simultaneously, sure doubling can be performed by monitoring dependent upon the analogue output.
